What are the Auto Selection and Manual Selection modes?

The TCK32 Series of load switch ICs (power multiplexers) provide the Auto Selection and Manual Selection modes, which allow selection between two power lines. In Auto Selection mode, the TCK32 Series determines whether VINA and VINB are within the normal voltage range and automatically passes whichever is at a normal input voltage to the output. When both VINA and VINB are within the normal voltage range, VINA is given precedence. In Manual Selection mode, the TCK32 Series selects either VINA or VINB according to the signal applied to the VSEL terminal.
